Great talk covering Blackfire and also application profiling in general. Clear explanations of the terms associated with profiling, and the benefits of why you should profile your code.
As I'm looking at this at the moment, I'd be interested in seeing how it could be integrated into a CI pipeline, and what metrics could be used to determine if a build passes or fails based on the results.
Would be a good talk for PHP meetups too.
A great overview of profilers and a deeper dive into backfire.io.
Slides were clear and we'll laid out. I've come away with more knowledge than I started with despite having used a few profiling tools.
Really interesting stuff and a very brief overview of some of the core D8 principles like dependancy injection and routing.
Felt like maybe a little too much was crammed in, a talk on just routing and services and DI would have filled the time easily.
I think next time focus more on the API and less on the gubbins of Drupal.
For a talk that was thrown together at late notice I thought you did a brilliant job!
